Displaying method for key information interface, establishing method for key information inference model, and electronic device using the same

An establishing method for a key information inference model, comprising:

• obtaining, according to a plurality of applications, a plurality of pixel data of at least one window frame of each of the applications;
• obtaining, according to the applications, at least one key information category and at least one key information item of each of the at least one key information category that a key information interface needs to display when each of the applications operates;
• and
• training the key information inference model using the plurality of pixel data, the key information categories and the key information items.

An electronic device, comprising:

• an application layer operation unit, configured to detect whether a hot key is triggered, wherein in an event that the hot key is triggered, the application layer operation unit detects a focused window;
• a data analysis unit, configured to obtain at least one window frame of the focused window and obtain a plurality of pixel data according to the at least one window frame;
• an artificial intelligence operation unit, configured to use a key information inference model to infer at least one key information category and at least one key information item of each of the at least one key information category of a key information interface according to the plurality of pixel data;
• and
• a hardware layer monitoring unit, configured to retrieve an information content corresponding to each of the at least one key information item, wherein the application layer operation unit is further used to display the at least one key information category, the at least one key information item and the information content on the key information interface.
